The use of the methyl viologen neutral species as a mediator

Journal Article (Journal Article)

The use of methyl viologen (MV) neutral species as a mediator for the reduction of CH I and the methanogenic bacterial nickel-containing cofactor F is reported. Solutions of MV were generated using a potential step electrolysis procedure in which MV is first generated at -0.6 V (Ag/AgCl) and then MV at -1.0 V (Ag/AgCl). The resulting spectrum of MV has a prominent peak at 367 nm with a shoulder at 398 nm and no peaks in the 525 to 625 nm region. Spectral and total charge transfer comparisons from spectroelectrochemical experiments as well as cyclic voltammetric studies of MV alone and with CH I and F , individually, provide evidence for the MV mediated reduction of CH I and F . To our knowledge, this represents the first use of MV as a mediator for the reduction of another species. © 1990. 3 430 3 430 3 430 0 .+ 0 0 2+ 0 0
